Wearing military medals
Army Regulation 670-1, "Wear and Appearance of Army Uniform and Insignia," allows retired soldiers to "wear all categories of medals (described in this regulation) on appropriate civilian clothing.
This includes clothes designed for veterans and patriotic organizations on Veterans Day, Memorial Day, and Armed Forces Day, as well as at formal occasions of ceremony and social functions of a military nature.
Personnel may wear either full-size or miniature medals. Personnel who wear medals on civilian clothes should place the medals on clothing in approximately the same location and in the same manner as on the army uniform, so they look similar to medals on the army uniform.
